The **Hr** display on a Samsung washing machine points to **water-temperature / heating-system error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **Hr**. Search normalization stores it as **HR** while preserving the characters a homeowner actually sees.

Quick answer
Water-temperature / heating-system error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so HR may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **Hr** display on a Samsung washing machine points to **water-temperature / heating-system error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **Hr**. Search normalization stores it as **HR** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits Hr is that heating may be weak, absent, excessive, or stop unexpectedly.
A symptom that fits Hr is that the appliance can pause when the control detects an unsafe or implausible temperature condition.
While Hr is active, drying, washing, cooking, or defrost performance may change depending on the appliance.
One clue that supports the Hr diagnosis is that hr appears during the washer stage associated with water-temperature / heating-system error.
Hr can be accompanied by this pattern: the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before requesting service for Hr, confirm the selected cycle or cooking mode is supposed to use heat.
Before requesting service for Hr, verify airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
As an external check for Hr, allow the appliance to cool before any owner-accessible inspection.
To rule out an accessible cause, do not open energized high-voltage or heating sections.
For Hr, start by doing this: record the code and the cycle stage where it appears.
The next non-invasive check is to check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For Hr, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
For Hr, the service threshold is straightforward: A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.

One controlled restart is reasonable after correcting an obvious external issue. A recurring **Hr** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **Hr** should not be ignored if performance is deteriorating or the display keeps returning.
No. **Hr** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer Hr** separate from same-looking codes used by other Samsung appliance families.
